My iPod shuffle is not recognized by my Window 7 laptop nor Macbook

" One of your USB device has malfunctioned and Windows does not recognize the device." ERROR 43 Please let me know how I can charge my Apple iPod Shuffle (4th Generation) without display. It does not display on the iTunes which I have downloaded from the net. I have bought a new charger dock, still showing same problem. Need help!

Apple stuff generally you have to return to apple - and they'll use what is called a 'factory jig' -- it connects physically to the device with the ability to wipe it clean and reinstall the system files. It's something they don't allow the public to use - since its closed source and gives access to the root of the machine.
